摘要

1. 古生代超序Rugosa在二叠纪-三叠纪界线处经历了多次危机,最终灭绝。其中最重要的一次是在弗拉斯纪-法门纪边界发生的全球性上凯尔瓦塞尔事件,导致所有珊瑚礁消失;它们在上法门尼亚时期(Strunian)重新出现。在很长一段时间里,法门纪的珊瑚世界(包括光带和暗带)都是一个未知的领域,但在波兰非典型法门纪Rugosa的专著(Rozkowska, 1969),以及主要在德国和摩洛哥以及中国北方发现了类似的动物群之后,这种情况发生了惊人的变化(Liao & Cai, 1987;Cai, 1988;Wu & Liao, 1988;郭1990)。关于法明期浅水Rugosa的知识增长得更慢:特别是通过Sorauf(1992:独特的第一上法明期,尽管来自北美的strunian前Rugosa动物群)和Berkowski(2002:第一上法明期,也是波兰Frasnian Phillipsastreidae的前strunian幸存者)。不幸的是,到目前为止,仍然没有确定的Rugosa出现在基础famenia(下、中、上三角掌肌区,也可能是下掌肌crepida区)。我所能收集到的唯一的Rugosa,与Nephranops incisus (Roemer, 1866)一起,是德国Harz山脉Rubeland的一个无法确定的大形态分类群。目前,上Givetian和Frasnian的非异型Rugosa是Rugosa

Review of some Frasnian ahermatypic coral localities from Germany and description of a new genus Spinaxon (Anthozoa, Rugosa, Upper Devonian)
1. IntroductionThe Palaeozoic superorder Rugosa passed through several crises before the final extinction at the Permian–Triassic boundary. The most important one, the global Upper Kellwasser Event at the Frasnian–Famennian boundary, led to the disappearance of all coral reefs; they reappeared during top-Famennian times (Strunian). For a long period, the coral world of the Famennian (both photic and aphotic zones) was a terra incognita – but this changed surprisingly after the monograph of Polish ahermatypic Famennian Rugosa (Rozkowska, 1969), and with the discovery of similar faunas mainly in Germany and Morocco, and also in northern China (Liao & Cai, 1987; Cai, 1988; Wu & Liao, 1988; Guo 1990). Knowledge about Famennian shallow water Rugosa increased more slowly: especially through Sorauf (1992: unique first upper Famennian, though pre-Strunian Rugosa fauna from North America) and Berkowski (2002: first upper Famennian, also pre-Strunian survivors of Frasnian Phillipsastreidae in Poland). Unfortunately, up to now there still are no certain Rugosa occurrences from the basal Famennian (Lower, Middle, and Upper Palmatolepis triangularis Zones, perhaps also Lower Palmatolepis crepida Zone). The only one Rugosa, which I could collect from the Middle Palmatolepis triangularis Zone, together with Nephranops incisus (Roemer, 1866), was an undeterminable ampleximorph taxon from Rubeland in the German Harz Mts.At present, the Upper Givetian and the Frasnian ahermatypic Rugosa are th

期刊介绍: Geologica Belgica is a Belgian journal that welcomes papers concerning all aspects of the earth sciences, with a particular emphasis on the regional geology of Belgium, North West Europe and central Africa. Papers not dedicated to the geology of Belgium, North West Europe and central Africa are only accepted when one of the authors is linked to a Belgian University or Institution. Thematic issues are highly appreciated. In this case, guest editors take in charge the selection of the manuscripts and the subject of the papers can be enlarged. The journal is in open access. Submitted manuscripts should be concise, presenting material not previously published. The journal also encourages the publication of papers from Belgian junior authors. Short letters are accepted. Papers written in English are preferred. Each mansucript will be reviewed by at least two reviewers.
